Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a centrifugal filter suitable for solid-liquid separation. Background Technology

[0002] Advances in materials science have also played a crucial role in the development of centrifugal filters. New filter materials and corrosion-resistant materials have enabled centrifugal filters to handle more complex materials, such as corrosive chemical solutions and high-temperature fluids. Meanwhile, in mechanical design, innovative designs such as automatic unloading devices and continuous feeding systems are constantly emerging, making centrifugal filters more convenient and efficient to operate, and able to meet the needs of large-scale, continuous industrial production.

[0003] Traditional filtration technology primarily uses filter media (such as filter paper and filter cloth) to trap solid particles, allowing liquid to pass through. However, when solid particles are small or easily clog the filter media, filtration efficiency drops sharply. Moreover, as filtration progresses, the filter cake gradually accumulates on the surface of the filter media, increasing filtration resistance and further reducing the filtration speed.

[0004] Solid-liquid separation is a common and important operation in industrial production and many experimental scenarios. Early solid-liquid separation methods mainly relied on gravity sedimentation and filtration. Gravity sedimentation is a simple method that utilizes the density difference between solids and liquids, allowing the solids to settle naturally in the liquid. However, this method is very slow, especially for systems with small particles or small density differences, which may take a long time to achieve effective separation. To address this problem, centrifugal filters, suitable for solid-liquid separation, were proposed. Utility Model Content

[0035] Reference Figure 1 , Figure 2 , Figure 3The water flow cleaning mechanism 2 includes a water pump 201. A fixed support column 202 is externally connected to the water pump 201, providing stable support and ensuring that the water pump 201 will not shake or shift during operation, thus guaranteeing the stability of the water flow output. A transport water pipe 203 is internally connected to the water pump 201 for transporting water. An injection pipe 204 is externally connected to the transport water pipe 203, injecting water into the annular pipe 205 connected to the injection pipe 204. The bottom of the injection pipe 204 is fixedly connected to... There is a ring-shaped pipe 205, and six spray nozzles 206 are fixedly connected inside the ring-shaped pipe 205. Water flows out through the spray nozzles 206 to achieve a cleaning effect. The supporting and fixing structure 3 includes a centrifuge tank 301.

[0036] Reference Figure 5The rotary opening and closing mechanism 4 includes a cylinder 401, which serves as the drive source, providing stable and powerful power support for the entire rotary opening and closing action. It efficiently converts pneumatic energy into mechanical energy through the reciprocating motion of an internal piston. A support and limiting block 402 is fixedly connected to the outside of the cylinder 401, providing a limiting effect for the movement of the first rotary limiting mechanism 403 and the second rotary limiting mechanism 404 connected to the support and limiting block 402. The first rotary limiting mechanism 403 is rotatably connected inside the support and limiting block 402, and together they rotate to achieve the desired effect. To achieve the effect of opening and closing the fan blades, the external fixed connection of the rotation limiting mechanism 403 is the rotation opening and closing fan 405, which drives the rotation opening and closing fan 405 to rotate together. The internal rotatable connection of the support limiting block 402 is the rotation limiting mechanism 404, which provides a limit for the movement of the rotation limiting mechanism 404, fixes the space when it moves, and reduces the occurrence of displacement events. The external fixed connection of the rotation limiting mechanism 404 is the rotation opening and closing fan 406, which drives the rotation of the rotation opening and closing fan 406, thereby achieving the effect of opening and closing the fan blades.

[0037] Working principle: When solid-liquid separation is required, the motor 101 is started, which drives the first rotor 102, the rotating track 103, and the second rotor 104 to rotate. This, in turn, drives the linkage column 105 connected to the second rotor 104 to rotate, thereby driving the fixed support block 106, the coarse filter screen 107, and the fine filter screen 108 outside the coarse filter screen 107 to rotate. This achieves the effect of centrifugal separation of solid and liquid. The separated liquid flows out through the outlet 1010 connected to the second fixed support block 109, while the separated solid remains. Inside the coarse filter 107 and the fine filter 108, when it is necessary to discharge the solids inside the coarse filter 107, the movement of the cylinder 401 drives the rotation limiting mechanism 404 connected to the cylinder 401 to move back and forth, thereby driving the rotation limiting mechanism 403 and the rotation limiting mechanism 404 to rotate. This, in turn, drives the movement of the 405 on the rotation limiting mechanism 403 and the rotation opening and closing fan 406 on the rotation limiting mechanism 404, thereby achieving the opening and closing effect and the effect of discharging the solids inside the coarse filter 107.

[0038] After the solids are discharged, the water pump 201 is started, which causes the water to flow through the transport water pipe 203 and the water injection pipe 204 into the annular pipe 205. The annular pipe 205 has a spray nozzle 206, through which the water flows out, thereby cleaning the internal coarse filter screen 107 and fine filter screen 108. The centrifuge tank 301 is fixed with a centrifuge cover 302 to provide support for the centrifuge discharge port 303 and fix the position of the motor 101 connected to the centrifuge discharge port 303, ensuring the operation of the mechanism.
